Nephroplasty in the Management of Hydronephrosis

“…There has been no short-term incidence of hypertension in this group. Other studies have shown no increase in the incidence of hypertension over longer periods following nephroplasty (Stewart, 1957;Collins et al, 1967;Smith, 1972).…”

“…This results in drawing the lower pole vessels towards the hilum of the kidney, away from the pelviureteric junction. This procedure, combined with freeing of any adhesions at the pelviureteric junction, gave encouraging results as a primary treatment in some cases of hydronephrosis (Stewart, 1957; Collins et af., 1967; Smith, 1972).…”

“…In a study of 100 nephroplasty procedures performed over a 10-year period (Smith, 1972) it became clear that in a group of patients where the pelviureteric obstruction was associated with marked intrarenal dilatation, nephroplasty in combination with pyeloplasty offered an additional bonus in that by compressing the dilated calices it reduced intrarenal dilatation and by elevating the lower pole it encouraged drainage from the lower pole calices.…”

A Comparison Between Urography and Radioisotope Renography in the Follow-Up of Surgery for Hydronephrosis

“…The procedures performed were dismembered ureteropyeloplasty (of the Hynes-Anderson type) 25 kidneys, Y-V ureteropyeloplasty 3, ureterolysis alone 1. Nephroplasty (Stewart, 1947;Smith, 1972) was done as an additional procedure in connection with 9 of the pyeloplasty operations, in order to reduce the calyceal volume. (When this had been done, reduction in calyceal volume alone was not considered a sign of improvement in the postoperative evaluation.)…”
